When I was a kid, school lunches didn't offer choice. I paid $1.10, and I was given four plops of foodlike substance. The entrees had names like "salisbury steak," "lasagne," or "beef stroganoff," but they all tasted about the same. Our "vegetable" was usually overcooked peas or green beans. There was a "starch," like mashed potatoes or a roll, and a dessert -- Jell-O or a cupcake -- typically the only edible item on the tray. If our lunch money wasn't stolen on the way to school, we were at least in theory presented with a balanced meal.
By the time my kids were in school, cafeteria philosophy had changed. Instead of serving up glop that no one ate, kids were given "healthy choices." They had charge accounts (no more stealing lunch money), and could select whatever they wanted to eat from a variety of options. What I don't understand is how the school nutritionists didn't realize that most kids were going to take three Jell-O's, two chocolate milks, and skip everything else. Jim regularly racked up charges of almost $10 a day. Needless to say, it didn't take long before we started resorting to homemade lunches.
I've finally found a study that addresses my concerns about putting children in charge of their own nutrition. A team led by Leonard H. Epstein gave 10- to 12-year-olds "budgets" to buy food in a laboratory setting. Then they varied the price of the foods to see if kids would modify their behavior: If we make junk food more expensive than healthy food, will kids substitute healthier foods?
In the first experiment, the kids were given bites of six healthy foods (like tomatoes, carrots, and grapes) and six unhealthy foods (like chocolate chip cookies, M&Ms, and potato chips). Each child picked their favorite healthy and unhealthy food. They were given $5 worth plastic tokens with which to "buy" their favorite foods, which they were told could vary in price. They were encouraged to buy as much as they wanted, since they could always save some for later. In one task, the price of the healthy food varied in $.50 increments from $.50 to $2.50, while the price of the unhealthy food stayed constant at $1.00. After each "purchase" was made, the kids got $5 more for the next purchase.
The results were as expected: kids bought more of the less expensive food -- whether healthy or unhealthy, and less of the more expensive foods.
But this experiment didn't exactly replicate the real world, since different kids have different amounts of money available to spend (and in the case of my kids' school, they had infinite budgets!). So Epstein et al. devised a new experiment, with 10- to 14-year-olds, this time varying both the budget and the prices of the items. When looking at only purchases of healthy or unhealthy foods, the results were similar to the first experiment:
For every budget level, as price went up, kids bought less of the item in question. However, the picture changes when we look at the relationship between price of one item (in this case, unhealthy foods), and purchases of the other item:
When we consider the low-budget group, as price of unhealthy foods increases, purchase of healthy foods increases -- this makes sense, and is in line with the first experiment. But for the high-budget group, as price of unhealthy foods increases, kids buy less healthy foods. Kids will spend an increasing portion of their budget to buy unhealthy foods, even as their price increases.
Epstein and his team note that overweight and obesity is increasing in America, but their experiments do suggest one way to help kids choose healthier foods: keep them on a limited budget, and increase the price of unhealthy foods compared to healthy ones.
Indeed, we've applied a similar tactic to our (now middle school-aged) kids' lunch budget. We give them $5 per day for lunch, and we allow them to keep the change for themselves. Suddenly the same kids who claimed they couldn't survive on the $7 to $8 they were spending in the school cafeteria are now spending $1 a day or less at the grocery store, making their own lunches, and saving the change for iPods and computer games. Whether this trade-off is ideal remains to be seen, but at least we're spending less on school lunches!

I had a similar situation with my schooling.
I grew up on lunches from home, until middle school where they actually had food that tasted good. I was suddently spending all my pocket change on healthy expensive food and expensive unhealthy food. For better or for worse, the school's budget changed and nearly every item that tasted good jumped about a $1 in price. This alone was enough to send me back to packing lunches.
But I knew kids that continued to spend $$ on food despite not having the money, often they ended up with no money in their account half way through the month and begged food off other kids, or just didn't eat.
that's a good plan with the money. I always do the same when given a stipend for food (ie at conferences) -- I spend as little as possible on food, which usually means I end up getting paid to go.
When I was in high school, my parents said I could buy lunch at school or make my own at home and they'd buy the stuff. I bought lunch at school every day, but I never spent more than $1.50 (which got me a bagel and cream cheese or a plate of fries and a sprite). I think your plan is a lot better than the one my mom and dad put forth, because I was too lazy to make my own lunch in the morning if I wasn't really gaining much from it.
maybe they should have only healthy food in the school, along with tasty alternatives to the junk food (there are many)? thats what my school did, and I grew up eating what the school provided, never really getting addicted to the junk food as most kids nowadays seem to be addicted to..
the graphs above would be quite different if unhealthy food was not an option :)
Jamie Oliver's project to make a healthy school lunch may be interesting. It's at http://www.feedmebetter.com/ . He has a very revealing timeline of the british school lunch. I laughed a bit at it at first, but the more I look at the project, the more it looks like a good idea (and less a celebrity stunt).
Brings me back. We had no choice and the cost was 35 cents. You always smiled and complimented the cook or server to get bigger and better portions! I thought the food was good, but there was not much change from day to day which made it boring to some. I was always very hungry in those days, so I didn't complain.
If we are truly concerned re obesity and youth; we need to go back to less choices and subsidize the "healthy food". We don't need to or would we want to eliminate "unhealthy food", since our youth need to learn to make good choices. Let's just help them along a bit.
We could eliminate some of the "killer unhealthy foods", like fries.
I just hope your kids aren't starving themselves at lunchtime just to save money for video games. :)

Trust me, that's not an issue with our kids! Not eating enough has never been their problem!
